As the Liverpool Echoreports, McCartney recently spoke to a group of students in his UK hometown at the Liverpool Institute of Performing Arts during an annual songwriting mentorship session, and he told them he's written a song about the United States' current leader.

He didn't specifically say whether it was in support of or against Donald Trump, just that: "Sometimes the situation in the world is so crazy, that you've got to address it."

As Billboardpoints out, however, some of the singer's past remarks seem to indicate that he's not a huge supporter of the current POTUS.

"I'm not a fan at all. He's unleashed a kind of violent prejudice that is sometimes latent among people," he told Australia's Daily Telegraphearlier this year. "He's unleashed the ugly side of America. People feel like they have got a free pass to be, if not violent, at least antagonistic towards people of a different colour or a different race. I think we all thought we'd got past that a long time ago."

Ahead of last year's U.S. election, McCartney posed for a photo with Democratic nominee Hillary Clinton, seemingly showing his support for her (or at least her support for him).

As previously reported, McCartney is currently working on a new album with producer Greg Kurstin. There's still no official release date for the record, but when it arrives, it will mark the follow-up to 2013's New. A coloured vinyl box set of early McCartney albums is available through Umusic.
